Probability — practice question

Georgie owns a red scarf, a blue scarf and a yellow scarf. On each day, she chooses to wear exactly one of these scarves. The probabilities of selecting the three colours are $0.2$, $0.45$ and $0.35$ respectively. If she wears a red scarf, she always also wears a hat. If she wears a blue scarf, the probability that she wears a hat is $0.4$. If she wears a yellow scarf, the probability that she wears a hat is $0.3$.
